"ChatGPT will write in your voice by referencing examples from your connected apps," an onboarding screen for a new feature reads.
OpenAI is testing a "Writing Style" feature
OpenAI appears to be testing a new "Writing Style" feature for ChatGPT that can learn how an individual composes text by looking at examples stored in apps the user connects to the service. The experiment is available to a small group of users, according to the reporting, and OpenAI has confirmed it is testing the capability. The company has not provided a timeline for a wider rollout.
Which apps are involved: Slack, Google Drive, Notion, Gmail
The onboarding screen shown in the reporting allows users to provide writing examples across three categories: Messaging, Documents, and Email. OpenAI lists Slack under Messaging, Google Drive and Notion under Documents, and Gmail under Email. Once a user configures the integrations, ChatGPT could reference the way that user naturally writes across those services when drafting new content.

According to the description provided on the onboarding screen, the change is in how users supply style signals to the model. Rather than repeatedly explaining a preferred tone or pasting examples into each conversation, ChatGPT would draw from existing examples in connected apps when composing messages, documents, or emails. The reporting frames the feature as a way to "write in your voice" by using real examples from a user's messaging and written archives across the listed services.
Relation to Anthropic's Styles and where this differs
The new experiment is compared in the reporting to Anthropic's Styles feature. Anthropic previously offered a personalization option called Styles that let users upload or paste writing samples to generate a custom style based on their communication patterns. The reporting says OpenAI's approach appears to take a different path by permitting reference to writing that already exists inside connected services, potentially giving ChatGPT a larger, more varied set of real-world examples — for instance, how a person writes short messages in Slack versus longer emails in Gmail or documents in Google Drive and Notion.
What this means for end users, technologists, and enterprises
- End users: People who opt in could see ChatGPT draft content that reflects examples drawn from their messages, documents, and email, reducing the need to restate tone preferences in each conversation.
- Technologists and platform integrators: Engineers and product teams will be the ones configuring and enabling the listed integrations (Slack, Google Drive, Notion, Gmail) for users who choose to connect them, since the feature relies on accessing material inside those services.
- Enterprises and procurement leaders: Organizations considering whether to allow connections between employee accounts and the feature will be deciding whether to permit use among a small test group now, with the timing of any broader deployment still unknown.
OpenAI has confirmed the Writing Style experiment is underway, but the company has not said when or whether the capability will reach a broader user base. The immediate facts are straightforward: the onboarding screen promises voice-mimicking by referencing connected apps; Slack, Google Drive, Notion, and Gmail are listed as example sources; and the experiment is distinct from earlier upload-and-paste personalization approaches such as Anthropic's Styles. How and when this moves beyond a small test group remains the open detail.
